How much data do I need for a week in Guernsey?
It depends on how you use your phone. Light use (maps, messaging, browsing) takes about 0.5–1 GB a day; scrolling a lot of social video can take 2–3 GB or more. Typical use per hour:
- Instagram Reels, TikTok: 0.3–1 GB

Does a Guernsey eSIM come with a phone number?
Most travel eSIMs, including most Guernsey plans, are data-only and have no local number. You keep your usual number on your main SIM for calls, texts and WhatsApp. Plans that include a number or minutes say so on the plan page.
Will my phone work with a Guernsey eSIM?
Yes, if it supports eSIM and is not locked to a carrier. To check, dial *#06#: if an EID number appears, your phone supports eSIM. Most iPhones from the XS/XR on, Galaxy S20 and later and Pixel 3 and later do, except most models sold in mainland China and some sold in Hong Kong and Macao.
Can I keep my own SIM and WhatsApp while using a Guernsey eSIM?
Yes. Your eSIM and your main SIM can be active at the same time. Use the eSIM for mobile data with data roaming on for that line, and turn data roaming off on your home SIM to avoid charges. WhatsApp keeps working on your usual number.

I've tried so many esim apps, but MobiMatter is always the cheapest and with the best overall packages. Great customer service as well. Highly recommended!

I accidentally deleted my e sim and couldn’t download it again so I talked to costumer service and they worked for like 2 hours to sort everything out for me and at the end everything worked again 100/10 service

I recently used their service and I’m extremely satisfied. The package lasted longer than expected, and I was able to make great use of it across the Asian region. They also have the fastest support team — very responsive and incredibly detailed in the information they provide.

Since I started using MobiMatter, I have never once encountered a problem that they haven’t responded to almost immediately. I guess this is what sets them apart. Excellent customer service, very detailed troubleshooting instructions, and a support team that genuinely follows through until the issue is resolved. The app is easy to use, the eSIM installation process is straightforward, and the profes are competitive. Highly recommended for anyone who wants reliable connectivity while travelling.

I used it smoothly and quickly in the Netherlands, Belgium, Germany, Spain, and Bulgaria. Sparks connects to the most suitable network for your location at that moment, allowing for convenient use. Depending on your travel plans, annual options are very advantageous because it consumes very little internet data there, unlike in Türkiye.

Purchased eSIM in Australia and set it up in Azerbaijan. Having never used an eSIM before, I had a few ‘user issues’. These were sorted out very quickly via email and me sending a screen shot of my ‘attempted’ setup. Technician got back to me in very short order with some simple instructions and now all good. Great efficient service.

I needed an eSIM for EU and non-EU counties for the same trip. They had one package at a great price that worked great in all location. The app was great as I was able to check my data balance, in real time, quickly and easily during my trip. Would definitely use MobiMatters again. Downloading the eSIM was quick and easy too. In addition, when I reached out to Customer Support on a minor account issue, they were very responsive and addressed my issue quickly and effectively.
